Reviewer 1 Report
The paper presents the validation of a device for emitting LED light to be included in the room of a MEG brain scanning device, designed and patented with reduced electromagnetic noise, to be used in future experimental studies of brain measurements of color perception. While the topic and the work are valuable and interesting, the paper needs reshaping:
- The introduction does not adress in a focused way the design of such devices, rather explains briefly the psychological effects of color vision, which seems irrelevant. The same is observed in the discussion section, instead of describing the implications of the conducted device validation.
- It seems that the Annexes and the text can change places. For example, the ...."notations of color conversion"... in section 3 can be given in an Annex, whereas Figure A1 can be inserted and explined in the text.
- The paper will benefit from explaining in the introduction the previous work [ref. 22] and the patent, and clarify better the novelty in the current context.
Multiple repetitions are observed in the text (e.g. the need for wired connection instead of Bluetooth...) as well as some language issues for better readability.
In overall, the paper will be publishable, after its reshaping towards a more focused description of the presented work, as well as, possibly, rephrasing the title, too.

The paper presents the validation of a device for emitting LED light to be included in the room of a MEG brain scanning device, designed and patented with reduced electromagnetic noise, to be used in future experimental studies of brain measurements of colour perception. While the topic and the work are valuable and interesting, the paper needs reshaping:
Q1. - The introduction does not address in a focused way the design of such devices, rather explains briefly the psychological effects of colour vision, which seems irrelevant. The same is observed in the discussion section, instead of describing the implications of the conducted device validation.
A1. Agreed. Introduction and discussion sections are revised. Structure of the manuscript has been changed.
Q2. - It seems that the Annexes and the text can change places. For example, the ...."notations of color conversion"... in section 3 can be given in an Annex, whereas Figure A1 can be inserted and explained in the text.
A2. Very valid remark. Indeed the technical solution is a result which we now show in the main text. Part of colour conversion is moved to the Supplementary in the revision.
Q3. - The paper will benefit from explaining in the introduction the previous work [ref. 22] and the patent, and clarify better the novelty in the current context.
A3. Revised accordingly to better link the previous research on the colour influenced judgement and UV-lamp compatible with MEG scans.
Q4. Multiple repetitions are observed in the text (e.g. the need for wired connection instead of Bluetooth...) as well as some language issues for better readability.
A4. Thank you. Revised and language editing was made by native English speaker who is co-author.
Q5. In overall, the paper will be publishable, after its reshaping towards a more focused description of the presented work, as well as, possibly, rephrasing the title, too.
A5. Revised.
Reviewer 2 Report
Summary:
This paper describes a novel USB-based device and associated software to control the RGB and Amber colored LED lamp for carrying out MEG brain scan. The proposed approach has been showed successfully controlling the LUME-20R lamp located inside the MEG scanner via USB from outside the electromagnetic shielded room. The results also demonstrate that the color controller software is capable to tune color saturation of and a range of color combinations including all the colors in spectrum, white light options and color hue, saturation and brightness, etc. The manuscript is well organized though a few places can be further improved.
---------------
Major Review:
1. Page 5&6:
Figure 2&3. Can the authors explain a little bit more of the meaning for maps in figure 2&3? Why there are regularly distributed scraps pattern in the map? What the deeper colors represent on the maps?
2. Page 7:
Figure 4. Can the author provide the brain map with 4 different lights, respectively? Can the author provide a little bit more detailed explanation for the meaning of this figure?
---------------
Minor Review:
1. Page 6
These data were first plotted on to color map base on its amplitude …
=> base => based?

Round 2
Reviewer 1 Report
The paper is improved to a large extent. It is very well structured and all sections are in the right place. The abstract is very good and has to be followed in the structure of the paper.
A few minor improvements can still be made:
1. The very first paragraph seems unnecessary and is not linked contextually to the paper. Can be removed.
2. The introduction better to conclude with something like the following: "The aim of the presented work is to design software for..... The paper is organised as follows..."
3. Several of the paragraphs about the experimental study repeatedly state that the aim is to desgn a lamp... Please, rephrase in a more coherent for each section way...
The Discussion section is appropriate, the figures are explained better. Each figure can be a bit wider explained in the text, since they are compound and compare different states - not just in the caption.
In overall, the paper is interesting, valuable, useful and well written. The minor improvements are required to be completely publishable.

Answer: Agreed. Moved to Supplement and served there as introduction.
2. The introduction better to conclude with something like the following: "The aim of the presented work is to design software for..... The paper is organised as follows..."
Answer: Very good point. Rephrased.
3. Several of the paragraphs about the experimental study repeatedly state that the aim is to design a lamp... Please, rephrase in a more coherent for each section way...
Answer: Rephrased and edited for better reading.
